Magnetic moments of doubly heavy baryons in light-cone QCD

Abstract

The magnetic dipole moments of the spin- 1/2 doubly heavy baryons are extracted in the framework of the light-cone QCD sum rule using the photon distribution amplitudes. The electromagnetic properties of the doubly heavy baryons encodes important information of their internal structure and geometric shape. The results for the magnetic dipole moments of doubly heavy baryons acquired in this work are compared with the predictions of the other theoretical approaches. The agreement of the estimations with some (but not all) theoretical estimations is good.
